Area of application: Personal grounding tester for daily testing of all relevant personal grounding products such as shoes or wrist straps Before accessing the EPA, the ESD protective measures such as HGB and dissipative shoes should be tested for proper function. The device is portable and can be used anywhere due to battery operation. Future-proof The limit values and associated calibration can be set by the customer, very one s main features: Resistance ranges can be set by the customer himself with reference resistorsCalibration is possible with reference resistors himselfwith potential-free relay contact for door opening or similar.With 100 measurements per day and 5 days per week, a set of batteries (4x AA-Mignon) lasts approx. one yearPlug-in charger in connection with NiMh - batteries for stationary continuous operation optionally availableseparate measurement of left and right shoe Scope of delivery:Test deviceConnecting cableShoe electrodeInstruction manualBatteries not included!
